Out of the Blue are an all-male a cappella group from Oxford University made up of 14 members. In 2011 Out of the Blue were ranked as the second best a cappella group in the world and are the UK Champions.

Out of the Blue made it through the first set of auditions of the 2011 Britain's Got Talent. They took to the stage and sang originally arranged versions of Lady Gaga’s Bad Romance and Justin Timberlake’s Sexy Back for the panel and received a standing ovation.

Blessed with great voices, Out of the Blue perform everything from classic barbershop to more contemporary pieces and they have a great repertoire and deliver fantastic performances.
